Problem with BT Home Hub 3

[jaypeecee]

Hi Folks,

I had a BT Home Hub 3 installed today on a BT Infinity line. BT Infinity is BT's (optical) fibre to the cabinet (FTTC) superfast broadband connection. The problem is that, having connected my Sure Signal to the Home Hub via Ethernet, the Sure Signal doesn't work anymore. I tried holding in the reset button, then disconnect power, then reconnect and when the power LED came on, released the reset button. The two white LEDs then came on, flashed for a while and then stopped. I see that others have had problems with a BT Home Hub but I'm not sure what the solution is. Any suggestions, please?

It's enough that you think they did. 😉

All this does shed some light. The most important thing it to make sure your six ports are open. This is required for the VSS to work properly through your internet router. If you don't open them the router firewall software will stop all the traffic as unwanted.

The DMZ option is called the "De-Militerised Zone" and opens all ports for the referenced device. It is very useful to make sure that the port restrictions I mentioned above are not stopping the signal getting through. It should only be used temporarily as it can be a bit of a security risk as, for the device put into the DMZ is now going around the firewall software in the router.

I did not actually put my BT fibre router into the DMZ myself as, when I manually did the ports, the VSS came up and worked. I did need to do a power cycle by disconnecting and then reconnecting the power (not a factory reset) in order to make the VSS pick up it's IP from the router using DHCP. Until that is done the router does not know what IP to apply the firewall rules to.

In the menu of the BT router you should find under the section on ports their is an option to apply a device to the DMZ. I think you apply it using the devices MAC code and then, when it gives the device an IP under the DHCP function, the DMZ is then applied to that device.

I think the explanation of what happens is propbably more complicted than it is in practice.

I have lots and lots of problems with BT Infinity and my VSS and eventually I had to use another more advanced router to get the VSS to work using Jumbo Framing on PPPoE. Some people get their BT Fibre router to work and others do not. At the moment the problem seems to be a bit random and BT are looking at it.

HTH.

Hi Folks,

Thanks, Jim. Before I try your suggestions, I will wait until Dave has looked at the information I provided in response to his request. I can't understand why the traceroute failed to connect with Dave's suggested IP address. That would suggest to me that perhaps the problem is not related to the VSS. This is a real pain and I'm not sure how I want to handle it. I have a stack of things that need doing and I can well do without this hassle.

Let's see what Dave has to say.

Hi JPC, your traceroute looks OK to me but Dave is the man to comment properly. Some routers on the wide area network do not respond to traceroute requests and respond with a blank. This does not mean it has failed just that you cannot determine that it has succeeded.
